Ozzy Osbourne has canceled the final four dates on his North American tour.

The rocker was hospitalized last weekend after undergoing emergency surgery for an infection in his hand.

Rolling Stone said the rocker will require more surgery, so the shows have been put off until 2019. The tour is scheduled to pick up in Dublin on Jan. 30.

“I’m so … bummed about cancelling these shows,” Osbourne said in a statement. “The tour had been going great and we were really looking forward to these last few gigs. We’re hoping everyone will be patient and we’ll look forward to seeing them at the shows next year.”
